SPECIAL OFFER:  A free Oil SAE30 for 4 stroke machinery 1 litre is available when you order 1 item or more of selected products.

A robust mower, designed to provide an excellent finish on all lawn types.

The amount of power a lawn mower has influences the quality of cut. Choosing the right lawnmower for your lawn is very important. This Mountfield HP425 lawnmower is suited for small to medium gardens of around 20m x 20m.

Honda-powered reliable performance

A reliable easy start GCVx145 OHC 4 stroke 145cc Honda engine which runs on unleaded petrol. This is a hand propelled mower, which means the engine drives the cutting blades and the operator pushes the mower forward across the lawn.

Excellent cutting performance

This lawnmower has a 41 cm /16-inch cutting width with an easy recoil start system. You can choose from one of 5 different heights of cut from 22 - 65 mm, which can be done using a single lever. Different heights of cut allow the operator to choose the length of grass to suit the finish of their particular lawn. 

Just the right cut for your lawn

The HP425 utilises a 4 in 1 cutting system, where you can collect, mulch, rear or side discharge depending on the finish you are looking for.

The collect feature means grass cuttings are collected into the large 60-litre grass bag. The grass bag alarm will also indicate when the bag is full, so the operator knows when to empty it.

The mulching feature recycles the grass clippings back into the lawn, saving you time and effort emptying the grass bag. The grass clippings that are recycled feed the soil and provide extra nutrients. This machine includes a mulch plug, so you will be ready to mulch as soon as you install it.

The rear discharge feature allows grass cuttings to be discharged at the rear of the mower, again saving the need to collect them.


This machine comes with a 5 year warranty.
